燃气管道不停输带压开孔封堵技术

Technology of Non-stop Transport with Pressure Hole Sealing Applied on Gas Pipeline

燃气管道不停输带压开孔封堵技术的特点为作业全程都在密封状态下进行,安全可靠,能保证正常供气,无资源浪费。该技术的核心设备有:开孔机、封堵器、下堵器、夹板阀、管件。文中着重介绍该技术在钢管型燃气管道的应用原理及实际作业中的操作规程,并介绍了其在实际应用中的不足。

The characteristics of the technology of non-stop transport with pressure hole sealing applied on gas pipeline is that the entire operation is in sealed condition. It is safe and reliable, guaranteeing the normal gas supply, and there is no waste of resources. The core equipment of this technology are tapping machine, plugging machine, underside stopper, flush valve, and fitting. This paper focuses on the application principle of this＂ technology in gas pipeline of steel pipe type and operating instruc- tion in the actual operation.This paper expounds its insufficient in practical application.
